ADJUSTABLE SOCKET FOR MORTARS.

SPECIFICATION forming part of Letters Patent No. 366,427, dated July 12, 1887.

Serial No. 234,917. (No model.)

To all whom it may concern.-

Be it known that I, EDMUND G. PURDY, of Ballston Spa, in the county of Saratoga and State of New York, have invented a. new and Improved Adjustable Socket for Mortars, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure 1 is a perspective view showing the application of my improved adjustable socket to a druggists mortar, and Fig. 2 is a plan view of the adjustable socket detached from the mortar.

Similar letters of reference indicate corresponding parts in both views.

The object of my invention is to provide a simple and effective device for application to mortars of different sizes for holding them while they are employed for pulverizing or tri turati ng substances.

My invention consists of a ring made in segments adapted to be drawn together or separated, so as to bring them into engagement with the outer surface of the mortar.

It also further consists in notches formed in the segments and adapted to receive lugs projecting from the base of the mortar.

The socket A is formed of a number oflike curved segments, B, each of which is provided with a semicircular notch, a, in its inner surface, at the center thereof, and furnished upon the outer surface with an ear, I), which is apertured to receive the screw 0, by which the socket is fastened to the counter or othcrsup' port. The ear 1) serves both as a fastener and as a strengthener of the segment B at the point weakened by the notch a'. The ends of the segments are provided with radial ears (I d, which are apertured transversely parallel with the plane ofthe ring, and in each ear dd is inserted a bolt, 6, provided with a winghead and extending through the ear d of the adjacent segment, where it is provided with a wingnut, e.

The mortar G is provided with lugsf, fitted 5 to the notches a of the segments. The socket A is fitted to the mortar G by turning the wing-nuts e in one direction or the other upon the bolts 0. d

When the socket is adjusted to the mortar in connection with which it is to be used, it is secured to the counter or other support by screw-bolts a, passing through the ears I) and through slots in the counter. The mortar is prevented from turning by the engagement of the notches a. with the lugs f, projecting from the mortar.

It is obvious that the segments B may be provided with elongated ears b, which may be slotted, and thus obviate slotting the counter. Therefore I do not limit or confine my invention to the exact form shown and described.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. An adjustable socket for mortars, consisting of segments adapted to engage the sides of the mortar, and means, substantially as described, for adjusting the segments.

2. An adjustable socket for mortars, formed of the segments B, provided with ears d d, the bolts 6, passing through the ears and provided with wingnuls e, and fastening ears b, substantially as described.

3. An adjustable socket for mortars, formed of the segments B, provided with notches a and having ears I) (Z d, and the clamping-bolts 6, provided with nuts 6, substantially as described.

4. The combination, with the mortar 0, pro vided with lugsf, of the socket A, formed of segments 13, provided with notches a, ears I) (l d, and furnished with clamping-bolts e, having wing nuts 0, substantially as described.

EDMUND G. PURDY.
